URDF question: origin
Can anyone tell me
<origin xyz="${x_loc} ${y_loc} ${z_loc}" ...>
means what? In my view it is number like 0,1 that should be after xyz=
, but not the ${x_loc}
thing.
Additionally, I'm trying to mount an arm on turtlebot in URDF, is it OK to add turtlebot pan's origin parameter to origin parameter of arm base link? Or there exist other ways?
Thanks so much!
